Here is my question why not put the carb heat on just prior to entering the pattern and power reduction AND LEAVE IT ON right up to short final and the runway is assured and where if you need full power for a go-around you have it and you will not be getting unfiltered air if landing on a dirt strip.
What’s the downside of leaving it on throughout the entire pattern till short final compared to the risk of picking up icing late on finals after you have "checked" for it back on the downwind and returned it to cold?
Carb heat should be used in accordance with the engine manufactures manual or when the engine shows signs of accumulating carburettor ice.
There are occasions when using the above method could actually induce carb ice if the atmospheric conditions are right, not one size fits all.

Unless you have an injected engine when you cease worrying.
Not true, it is possible to get induction icing, hence the fitting of an alternate air source.
